JP6957639B2 - Resource allocation signaling - Google Patents

Description

This disclosure relates to wireless communication technology, especially in the context of radio access networks (RAN) for 3GPP 5th generation (5G) standards such as New Radio (NR).

For example, modern wireless telecommunications systems with NR can use a wide frequency range for communication. Devices communicating using such systems use part of the frequency range to transmit and receive according to resource allocation (or scheduled resources). Such allocations are usually signaled by control signaling. It is difficult to specify consistent control signaling that can flexibly cover a wide frequency range while having an acceptable level of signaling overhead.

An object of the present disclosure describes an approach that utilizes consistent allocation signaling that has limited overhead over a wide range of frequencies, while at the same time allowing flexible allocation of resources, especially considering various allocation sizes. It is to be. The approaches described herein are particularly useful in the context of NR wireless access technologies / networks (NR LAT / RAN). Therefore, the assigned radio node or network node may in particular be a gNB (or eNB in some cases).

Therefore, a method of operating a radio node in a radio access network is disclosed. The method comprises communicating using frequency resources based on the allocation information received in the message, and the message has an allocation information structure that includes the allocation information.

In addition, radio nodes for radio access networks may be considered. The radio node may be adapted to communicate using frequency resources based on the allocation information received in the message, and the message has an allocation information structure that includes the allocation information. The radio node may in particular be a user device or terminal, or a more generally assigned radio node, which may obtain resources allocated (configured) by another (assigned) radio node. Such assigned radio nodes may be, for example, relay nodes, or, for example, booster nodes or secondary nodes in dual connection and / or heterogeneous network configurations. The radio node or assigned radio node may include processing circuits and / or radio circuits, particularly transmitters and / or receivers and / or transceivers, and / or transmitters and receivers for communicating and / or receiving messages. Alternatively, they may be adapted for use. Alternatively or additionally, the radio node may include a communication module for communicating messages and / or a receiving module for receiving messages.

It also describes how to operate an assigned radio node in a radio access network. The method comprises sending a message that includes allocation information, and the message has an allocation information structure that includes allocation information. The method may also have to determine allocation information, eg, based on scheduling one or more (assigned) radio nodes and / or in the context of scheduling. It may be run by a wireless node or another node.

In general, scheduling may be considered as a process in which resources are distributed for radio nodes and / or data streams (which may be associated with radio nodes). In the context described herein, the allocation may relate to notifying the radio node of the resources scheduled for it, for example by sending a message containing the allocation information.

Assigned radio nodes for radio access networks may be considered. The assigned radio node is adapted to send a message containing the assigned information, and the message has an assigned information structure containing the assigned information. Assigned radio nodes have and / or are adapted to utilize processing circuits and / or radio circuits, especially transmitters and / or transceivers, for transmitting messages and / or determining allocation information. May be good. Alternatively or additionally, the assigned radio node may include a transmit module for transmitting the message and / or a decision module for determining the message. The assigned radio node may be a network node in particular.

Allocation information may generally be considered to be the formation of control information. The message may be a control information message and / or may represent control signaling. In particular, the message may be implemented as a downlink control information (DCI) message, which may be considered to represent a downlink message containing control information specifically for NR. The allocation information may be included in a single message, for example, for a single allocation occurrence. In some variants, the message may be considered a system message (eg, broadcast or multicast in the context of random access or sidelink resource allocation), or an RRC or MAC (medium access control) layer message. In the context of sidelink resource allocation, the allocation may indicate frequency resources available for one or more pools, such as discovery pools and / or communication pools.

The allocation information structure may generally indicate the arrangement of information representing the allocation information, for example by the formation of bits. The structure may indicate the meaning and / or how to interpret and / or decode the meaning for providing or reading the allocation information.

The allocation information structure may be considered to include a header containing header information and a bitmap containing mapping information. The header information and mapping information may be considered as allocation information.

The header information may indicate the type of resource grouping used for the allocation and / or its location within the bandwidth or bandwidth representation to which the allocation information, in particular the mapping information, is relevant. The header information may derive mapping information, for example, to facilitate correct coding or decoding. However, the header and mapping information in the message is optional, given that the order is defined and known (eg, pre-defined and / or configured) for the radio node and / or the assigned radio node. Order or dispersion of may be used.

The position may indicate part of a bandwidth of a particular size, and in some variants the frequencies may be continuous or discontinuous (frequency split). .. The size may correspond to the Wth portion of the total bandwidth / its representation (1 / W of the bandwidth). W may correspond to the size of the largest possible resource grouping type divided by the size of the resource grouping type used for the allocation (eg, indicated by the header information). The resource grouping type and the maximum resource grouping type may be elements of a set of resource grouping types.

The location allocation information may be considered as information indicating which resource grouping of the types indicated in the header information within the location is allocated (or not allocated) to communicate with the radio node. Groupings may be assigned according to, for example, mapping information, eg, bitmaps. Specifically, each bit in the bitmap may be mapped to one (eg, different) grouping within a position that indicates whether a resource within the resource grouping is allocated.

According to the approach described in this book, the portion of the bandwidth that can be allocated in a single message may be scaled according to the size of the addressed resource grouping, but at the same scale (granularity). May increase (corresponding to decrease in resolution).

Header information generally indicates, for example, a combination of location and associated resource grouping types according to a predetermined (eg, pre-defined, configured, or default) scheme for associating location and type. It may be considered. Such a scheme may be represented, for example, in a table such as the same table as in Table 1. Multiple positions may be associated with a resource grouping type, and in particular W positions may be associated with one type (W varies for types of various sizes). A set of resource grouping types is represented by a set of positions, which in particular is all positions (part of the bandwidth) that can be assigned and / or dealt with by the resource grouping type associated with the set. ) May be considered. Each position in the set may be represented by a bit combination in the header. Types may be implicitly linked to a bit combination or order of position. Table mapping positions (and implicit or explicit types) for bit combinations of header information may be considered. The table may be available, eg, pre-defined or configured, and / or stored in memory for the radio node or the assigned radio node (each circuit) to determine or decode the allocation information.

Further, the header information indicates whether the allocation information is related to a bandwidth representation (eg, 1 bit) and / or which bandwidth representation (eg, multiple bits) is related to, and / or the representation (physical). It may be considered that it may include a representational indication indicating which mapping should be used to map to the bandwidth.

Frequency resources may generally be included in a bandwidth that may be carrier bandwidth and / or system bandwidth and / or user equipment bandwidth. The carrier bandwidth may be the bandwidth of the carrier used for communication, which may be an uplink carrier or a downlink carrier. The system bandwidth may be the bandwidth that the assigned radio node and / or RAN) may utilize, or may be adapted or configured for utilization (eg, on the carrier). The user equipment (UE) bandwidth (or more generally the radio node bandwidth) is adapted and / or configured for use by the radio node / user equipment according to, for example, its own radio circuit and / or configuration. It may be bandwidth. The UE bandwidth in some variants may be less than the system bandwidth and / or carrier bandwidth, for example due to circuit limitations of the UE. Similarly, carrier bandwidth may differ from system bandwidth, for example due to circuit limitations and / or operating conditions. Bandwidth may generally be the bandwidth allocated for communication and may be referred to as total bandwidth. Note that this does not necessarily mean that the total bandwidth is allocated to one radio node, or even to two or more radio nodes, and that frequency resources within the bandwidth are allocated. Bandwidth may represent the bandwidth available for communication on the associated carrier and / or for the system and / or UE or radio node. Bandwidth type differences may be corrected in control signaling, especially allocation information, by not allocating certain resources that are not available to the radio node or UE, for example.

In general, the frequency resource may be included in the bandwidth, and the bandwidth consists of L bandwidth elements (L may be greater than 1 and may be, for example, 100 or more). Bandwidth elements may cover frequency intervals around the center frequency and / or may be associated with a particular frequency and / or subcarrier. Bandwidth elements may be non-overlapping and / or continuous (both may be considered for physical bandwidth and at least non-overlapping for virtual representation). Frequency resources and / or bandwidth may generally be allocated for uplink transmissions, or downlink transmissions (received by radio nodes), or sidelink communications. In some cases, resources and / or bandwidth can be used, for example, in the case of some Time Division Duplex (TDD) or when sharing a large bandwidth due to Frequency Division Duplex (FDD). It may be assigned for directional communication.

In general, the allocation information structure may include a header for header information, the header information indicating at least one resource grouping type to be allocated. The header information may indicate exactly one resource grouping type. The allocation may be such that frequency resources are allocated in a grouping of the indicated size. Alternatively or additionally, the header information may indicate the location of the indicated resource grouping or resource grouping type within the frequency domain and / or bandwidth or bandwidth representation. This may be related to the bandwidth or part of the representation that the resource grouping may cover. The location may represent a frequency interval corresponding to the size of the allocated resource grouping. Positions (possible positions) for a given type of resource grouping need not overlap in the frequency domain. For example, for resource grouping covering a quarter of the bandwidth representation, four possible positions may be considered so that these positions do not overlap (eg, at frequency boundaries, if any). They may be arranged continuously in the frequency domain (only in contact).

In general, the header may be determined based on the allocation size to be allocated (eg, total size or total number of resources, eg elements or blocks), and / or operating conditions, and / or the channel to be allocated. Determining the allocation information may include determining the header information and / or determining the bitmap, as described herein. Details of scheduling resources may be left for implementation in the assigned radio node or scheduler.

The various resource groupings may generally have different sizes (eg, referred to as R), especially in the frequency domain. The size (in the frequency domain) of a resource grouping (and / or its associated type) may also be indicated by the associated frequency interval and / or by the bandwidth elements and / or subcarriers and / or resource elements it contains. good.

A set of resource groupings or resource grouping types that may contain two or more of a bandwidth element, a bandwidth block, and one or more bandwidth block groups may be considered. The set may be pre-defined according to the standard, for example, and / or may be composed, for example, by an assigned radio node or another network node. In some variants, the sets may be configured such that different sets form the basis of resource allocation information, eg, at different times.

Allocation information may relate to frequency resources grouped into a resource grouping of a particular resource grouping type, which types include bandwidth elements and bandwidth blocks containing multiple bandwidth elements. It is one of a bandwidth block group containing a plurality of bandwidth blocks.

The header information may select and / or indicate one grouping type from a set of resource grouping types. The header may have a size (in bits), the size of which is the number of elements in the set of resource groups and / or the possible positions (in the bandwidth / frequency domain) of the grouping within the set. Determined based on the minimum number of bits required to represent a number, and / or specified by these, and / or at least these. The size of the maximum resource grouping for a set may be referred to as Rmax. In some cases, the maximum resource grouping of the set may cover (total) bandwidth (in frequency). The smallest resource grouping size for a set may be referred to as Rmin. The smallest resource grouping may represent a block, especially a resource block. However, in some variants, the smallest resource grouping may represent a bandwidth element. Any resource grouping with a size less than Rmax may be referred to as a subgroup, especially if it has a size greater than Rmin. The size of the allocation may be represented by the bandwidth or resource element allocated to communicate with the radio node, for example by message. Depending on the use case, the allocation size, especially for NR, may vary over several magnitudes.

Note that different (bandwidth) block group types may be specified for different sizes. The size of a bandwidth block group may be indicated by the number of bandwidth elements it has and / or the number of bandwidth blocks. Bandwidth elements may be represented by subcarriers and / or resource elements. Bandwidth blocks may be represented by subcarrier blocks and / or resource blocks.

The block may generally include a plurality of elements (eg, bandwidth block, bandwidth element, resource block, resource element). A block group may generally include multiple blocks, for example, a resource block group may include multiple resource blocks). The size of the block (eg, with respect to the elements within the block) may be pre-defined according to, for example, standard and / or default settings, and / or, for example, configurable and / or by radio nodes, especially network nodes. It may be configured.

The various types of grouping or grouping within a set of grouping types may have sizes that are related to each other according to power law, such as ^{K p, and K and P may be integers.} K may be particularly 2. P is 0 for bandwidth elements and may be greater than 0 for other grouping / grouping types. However, it may be considered that the smallest type of grouping within a set of groupings has A bandwidth elements, eg, a block (fixed and / or configurable) size. The various block groups may follow power law as shown herein, and K may then be related to the number of bandwidth elements and / or blocks within the group. In some variants, there may be power law with different K values for different block groups. The grouping sets may be ordered by size or may be orderable. From that perspective, the grouping settings are all possible types that follow the power law with the size of the maximum size block group and the minimum size grouping, eg, the size between the bandwidth element or the bandwidth block. Groupings may be included. However, there may be variants in which not all possible sizes according to power law are present in the set. In general, the size of a resource grouping may be considered to be the same as the size of a related type of grouping. The resource grouping or set of types may be determined so that they form layers of various sizes as determined by the layer-to-layer power law (layers are ordered by size).

In some variants, the allocation information structure may include a bitmap for the mapping information, which maps one or more resource groupings to a bandwidth representation. The one or more resource groupings may be of the resource grouping type of a set of groupings, for example as indicated by the header information contained in the message.

The bandwidth representation may represent a physical bandwidth or a virtual representation of the physical bandwidth. In this latter case, the utilization of frequency resources may be based on mapping the bandwidth representation to physical bandwidth. Frequency diversity and / or hopping may be configured with appropriate bandwidth representations. Bandwidth representations may be configured or configurable and / or time dependent. Bitmaps for mapping information may be in addition to headers as described herein and / or may follow such headers.

Allocation information, especially bitmaps, may indicate which groupings are allocated and / or not allocated for communication. Bitmaps may have a size B (in bits) that may be specified by a seal (N / R). In general, for each assignable and / or copingable grouping, one bit may be associated which may indicate whether or not the grouping is assigned. N is the smallest grouping type (eg, size Rmin for a bandwidth block or resource block or element) of the set of grouping types required to cover and / or specify (total) bandwidth. It may be the number of groupings. R may be Rmax of the set. Bitmaps may be thought of as mapping a 1 / W portion of the bandwidth for a grouping type that has 1 / W of the size of the largest grouping type (where W is particularly a power of 2, or More generally, it may be a power of K).

It may be considered that the allocation information structure may include a header having M bits and / or a bitmap having B bits. M is used to represent the number of possible groupings and / or to have at least enough (or just enough) bits to represent and / or for allocation signaling as described herein. To represent, and / or to have at least enough (or just enough) bits to represent the number of possible positions in all groups of the set of resource groupings to be done, or in some variants. It may be chosen to represent both independently. B may be chosen to have at least enough bits to represent the (eg, minimum) number of types of groupings that have the maximum size required to cover the allocated bandwidth.

Locations may generally be thought of as representing a particular part of the bandwidth / representation to which resource grouping is allocated. Thus, the position may represent a portion of the frequency space that may be continuous or discontinuous (eg, divided and have frequency gaps). This portion may be the total bandwidth for the largest size grouping type, as opposed to the smaller portion of the bandwidth for the smaller size grouping. Each possible position (each associated with a bit representation) may be associated with a particular size grouping type and / or grouping type. B bits in the bitmap may be used to deal with or allocate B resource groupings in position, resulting in bandwidth or bandwidth, depending on the size of the grouping indicated by the header information. Positions that cover specific parts of the representation may be assigned.

A set of resource groups, and / or which grouping is in the set, and / or the grouping type or maximum size of the grouping in the set (Rmax), and / or the minimum size of the grouping in the set (Rmin) and / Or number is bandwidth and / or associated carrier frequency and / or math and / or interval, and / or direction of communication and / or type of communication (eg, waveform, especially OFDM or SC-FDM), and /. Alternatively, it may be determined based on the allocated size. Any one or any combination of these set-related (or grouping-related) parameters may be pre-defined according to standards, for example, and / or configured or configured (eg, within pre-defined options). It may be possible. Thus, the radio node and / or the assigned radio node (scheduler or scheduling network node, respectively) may determine and / or detect such parameters based on the available communication parameters, and as a result, For example, explicit control signaling may not be required and / or, for example, higher level control signaling on the RRC layer (radio resource control layer) and / or control signaling during random access is sufficient. It may be sent less frequently than a particular DCI message.

The allocation information may be valid for a given time interval, eg, a slot and / or subframe and / or minislot and / or physical representation of a transmission time interval. Allocation information indicating the allocation of resources for the downlink (meaning reception by the radio node) may be within a time interval that includes the allocated resources. In some variants, this may also be valid for uplink allocations, but in many cases uplink allocations may relate to the time interval after the time interval in which the allocation information was received.

In general, the allocation information may be considered for allocating bandwidth frequency resources to radio nodes for communication. Communicating may include transmitting (eg, uplink or sidelink) and / or receiving (eg, downlink or sidelink) according to the allocation information. Communicating using a frequency resource means transmitting (and / or receiving) on the frequency resource allocated for transmission and / or reception on the frequency resource allocated for reception. May be provided. The allocation is not particularly dealt with in this document, but may include a time domain component, but may be indicated in the allocation information and / or message. Communicating may be based on receiving and / or decoding allocation information and / or identifying allocated frequency resources.

Also disclosed are program products comprising instructions for causing the processing circuit to control and / or execute any one of the methods described herein.

Further disclosed are carrier medium devices that transport and / or store program products as disclosed herein.

Allocation information may generally have a structure as shown in one of the examples described herein.

The bandwidth representation may generally represent virtual or physical (frequency) bandwidth. Virtual bandwidth is mapped or mapped to physical bandwidth in an unambiguous and / or unique and / or well-defined manner, for example, based on a bandwidth representation map that may be configured or configurable. It may be possible. Bandwidth representations are such that, for example, frequency intervals (eg, specific groupings associated with such intervals) represent physical intervals of the same size (in the frequency domain) so that all of their frequencies are represented. , The physical bandwidth may be sufficiently represented. The mapping between representation and physical bandwidth is particularly continuous from one contiguous frequency interval (including, for example, bandwidth elements ordered according to frequency) to another contiguous frequency interval, the (physical) bandwidth. It may be a target. However, the mapping is such that (at least some) continuous frequency intervals and / or adjacent groupings (with no gaps between them) of the representation are distributed and / or discontinuous in physical bandwidth. / Or may be discontinuous, as may be mapped to non-adjacent groupings. Note that physical bandwidth is a representation of itself and / or may be represented on the basis of a continuous mapping of isomorphism (which may be without topological holes).

Resource grouping, as indicated by the allocation information, is in a particular frequency range, using lower and / or higher frequency boundaries as defined, and / or at least with respect to bandwidth and / or within bandwidth (eg, for example. Resource grouping types are generally of a given size (in the frequency domain, eg, width), while they may be associated (with respect to the bottom edge of the bandwidth and / or the top edge of the bandwidth) unless specifically related to frequency. Or note that it may refer to a frequency interval having a range).

Communicating using frequency resources may generally include mapping allocation information to physical frequencies.

The frequency resources used may be considered as allocated resources. Frequency resources may generally be represented by resource grouping.

The approach described in this document uses a consistent approach to the allocation information structure to enable resource allocation over a wide range of bandwidths with a scalable granularity (depending on the size of the allocated group type).

The bandwidth element may represent a portion of the (frequency) bandwidth or frequency spectrum, respectively. Bandwidth elements may be continuous in the frequency domain and represent, for example, frequency intervals, such as intervals of a particular size. In general, the bandwidth element may be considered to represent the bandwidth in any part of the frequency spectrum. However, the bandwidth element may be associated with a frequency or carrier, for example, the frequency or carrier may represent the center frequency or representative frequency of the bandwidth that includes the bandwidth element. Bandwidth may include one or more bandwidth elements and / or may be composed of one or more bandwidth elements. In general, the bandwidth element can be considered, for example, as the smallest manageable frequency interval of bandwidth that can be dealt with for use as a resource and / or for signaling. Different bandwidth elements may have different widths (in frequency). The width of the bandwidth element may depend on the carrier or frequency associated with it and / or the bandwidth interval (eg, subcarrier interval) and / or the numerology used for the frequency or bandwidth associated with it. In some variations, for a given frequency or carrier (or numerology or spacing), each associated bandwidth, the bandwidth elements contained therein or associated thereto may have the same width. Bandwidth elements may be represented by subcarriers or resource elements (each of which may correspond to a subcarrier, its frequency domain component).

This document describes several types of (bandwidth) grouping. Grouping may refer to a single element (eg, bandwidth or resource element), or block, eg, a block of elements, where the block corresponds to a block group with multiple elements, or multiple bulls. It may cover the frequency range or interval to be used. Here, the block group may cover a plurality of blocks, frequency ranges or intervals corresponding to related elements, respectively. The frequency intervals covered by each of these groupings may be continuous in some cases, especially in relation to bandwidth representation. However, if the bandwidth representation corresponds to a discontinuous mapping of groupings to (physical) bandwidth, the intervals may be discontinuous / distributed within the bandwidth.

The message containing the allocation information may be considered as a form of allocation signaling (or control signaling).

The drawings are provided to illustrate the concepts and approaches described herein and are not intended to limit their scope. Drawings include:
An example of RB allocation for R = 4 and B = 2 is shown. Another example of RB allocation for R = 4 and B = 2 is shown. An exemplary radio node is shown. An exemplary assigned radio node is shown. An algorithm diagram of an exemplary method of operating a wireless node is shown. An exemplary radio node is shown. An algorithm diagram of an exemplary method of operating an assigned radio node is shown. An exemplary assigned radio node is shown.

An approach is described that combines the resolution of the bitmap for allocating resource groupings to the allocation size (grouping size), with separate blocks (or elements) such as RB (or RE) for small allocations. It is possible to indicate (even), while for large allocations bitmaps refer to block groups, such as large groupings such as RBGs. Therefore, efficient use of limited DCI resources may be provided and consistent use of signaling allocation may be facilitated.

An example is given using the following assumptions.
-The full bandwidth of N resource blocks (RBs) (which the UE can receive or transmit or is configured to receive or transmit) is provided.
-The (maximum) resource block group (RBG) size of R (Rmax) where R (Rmax) is a power of 2 (which may be derived, for example, from the UE or system bandwidth or carrier bandwidth). .. In this context, the value of R may vary based on the composition of the values, provided that the expected bandwidth value is derived based on what the UE constitutes (eg, UE bandwidth). Please note that. Moreover, the UE can also assume different values of R with different DCI messages, as not all messages can potentially handle enough BW to which the UE can be assigned. Also note that the values can vary between UL and DL. This can also be different in UL based on which waveform is used, i.e. if CP-OFDM or SC-FDM is utilized.
-M-bit "header"
-B-bit bitmap

Bitmap B = Seal (N / R) is provided to allow all resource groupings, eg resource blocks that are RBGs, to be addressed, especially for each resource block, grouping or group. There is one bit. In this example, resource element-based allocations are ignored. Note that the frequency component of the resource block described represents a bandwidth resource block.

Resource allocation is signaled to the UE in all M + B bits using a size M header followed by a size B bitmap. Resource allocations are sent in messages, such as DCI messages.

Hereinafter, these are referred to as RB and RBG. However, these terms are intended simply to refer to groupings such as bandwidth blocks and resource block groups, which may be interchanged accordingly.

The meaning / decryption of the resource allocation message may be explained using a table constructed along the following rows.
1. 1. One entry in which a bitmap of size B refers to an RBG of size Rmax (which may be assumed to cover the entire bandwidth if all are allocated).
2. Two entries where a bitmap of size B references an RBG of size Rmax / 2.
a. Bitmaps can handle RBs or RBGs with half the total bandwidth, so one for every half of the total bandwidth (there are two possible positions) and two entries are required.
3. 3. A bitmap of size B refers to an RBG of size R / 4 (having four possible positions).
a. Bitmaps can handle RB with a quarter of the total bandwidth.
4. Eight entries where a bitmap of size B references an RBG of size R / 8.
5. (…Such…)
6. RBGs whose bitmaps of size B refer to sizes R / R, that is, R entries that refer to individual RBs.

The above steps can be easily described as a general algorithm, for example, as follows.
1. 1. Let n = 0.
2. ^{Add 2n} rows to the table. Here, ^{for each of the 2 n} rows, the bitmap refers to an RBG of size R / 2 ⁿ , and the rows are associated with different (non-overlapping) subgroups of the RBG.
3. 3. Let n = n + 1.
4. If R / 2 ⁿ ≥ 1, then transition to 2 (eg, R / 2 ⁿ ≥ 2 or R / 2 ⁿ ≥ 4) if there is no need to support individual RBs or RB pairs, the algorithm Can stop earlier).

In step 2, the subgroups are as follows.
-For n = 0, all RBGs.
-For n = 1, the left half and the right half. Instead, even and odd RBs or RBGs (representing discontinuous positions).
-For n = 2, the 1st halves, 2nd quadrants, 3rd quadrants, and 4th halves of RBG. Alternatively, four different combinations 4 having offsets 0, 1, 2 and 3 (which also represent discontinuous positions; other variants may be considered; positions (or positions and types) of bits. Tables that map to combinations may be determined and / or specified and / or represented accordingly. Tables may be indexed and / or mapped by header information.

An example of Rmax = 8 is shown in Table 1. In FIG. 1, an example for Rmax = 4 and B = 2 is given. In examples such as LTE with N = 100 and Rmax = 8, the bitmap is size 13 and is a size 4 header, i.e. 17 bits in total. This setup allows allocation from a single RB to a total of 100 RBs.

RB subgroups (which may be groups of different sizes) may be continuous or continuous in frequency, eg, two adjacent resource blocks or groups are in the physical frequency region. May be placed next to each other in (this may refer to a position, or in some cases at least the physical frequency region). In some variants, it may be useful to improve the amount of frequency diversity, for example for some smaller allocations. This may be achieved, for example, by using frequency-divided positions.

The RBG or RB in the above description can refer to a virtual resource block or group, and a virtual-to-physical mapping function may be used to describe the physical location. In general, the frequency resources indicated by the allocation information, their respective groupings, may be considered to be related to the bandwidth representation, which may be a virtual representation. The bits in the header indicate whether the RB allocation points to a physical resource block or a virtual resource block (or, in the general case, multiple bits for describing multiple virtual-to-physical RB mappings). You may. Alternatively, the mappings may be configured separately using higher layer signaling, such as RRC signaling or MAC signaling.

In addition to or in lieu of this, the grouping, at least the grouping of the selected size and / or position, may be discontinuous (or discontinuous), as shown in FIG. In this case, the header information is one or more to indicate whether continuous / continuous (FIG. 1) grouping is assumed or discontinuous / discontinuous (FIG. 2) grouping is assumed as in RBG. It may have additional bits. If no such additional bits are provided, standard (predefined) specifications and / or configurations (eg, higher layer configurations such as RRC or MAC) will have subgroups of virtual RBs or groupings, and / or It may indicate whether to indicate a localized physical RB (FIG. 1) and / or a dispersed physical RB (FIG. 2).

In the above pseudo code, if the termination criterion "if R / 2 ⁿ >1" is ^{replaced with "if R / 2 n} > 2 ^L ", the minimum RB particle size is 2 ^L , not 1. Alternatively, particle size may refer to bandwidth elements as minimum grouping (instead of blocks). As a further alternative, the block size (minimum grouping) may be configured and / or configurable to provide greater flexibility.

The above algorithm will be described assuming that the PRB particle size is in ^{the form of 2 L.} However, if the RBG size is based on another exponentiation K ^r, the algorithm can be applied.

Table 1: Example of header size for R = 8

The resolution of the allocation information (bitmap) may be defined by the size of the grouping used, which may be considered to represent the size allocated to each bit of the bitmap.

The method of operating an allocated radio node such as gNB or enB is that each UE has its own allocated band based on the RBG size of the maximum RBG size (the size of the maximum grouping of the set) within the allocated BW portion. One or more radio nodes (particularly the UE) may be configured to have an aligned starting position of width (BW) and / or such nodes are configured in this way. May be adapted as such.

Signaling to set up on which BW a radio node such as a UE can run (eg, uplink signaling indicating UE bandwidth, and / or carrier and / or system bandwidth and / Or the control signaling that constitutes the UE bandwidth) is based on, for example, the maximum RBG size (generally the maximum grouping Rmax) utilized by one of the subcarriers within the system bandwidth edge or BW, especially the system BW. You may. Subcarriers can be provided, for example, by SS blocks.

FIG. 3 schematically shows a wireless node or terminal or wireless device 10 which may be implemented as a UE (user device) in particular. The wireless node 10 includes a processing circuit (which may also be referred to as a control circuit) 20 which may include a controller connected to memory.
